The model uses a Weibull- inter-arrival times based count process and a copula to produce a bivariate distribution for the number of goals scored by the home and away teams in a match. Y/σ has a chi distribution with 1 degree of freedom. If all you're trying to prove is that the mode of the Poisson distribution is approximately equal to the mean, then bringing in Stirling's formula is swatting a fly with a pile driver. They find that the assumption of independence is not rejected in 15 cases out of the 24. Bivariate distributions -- Example 1.
